Here's the code.. http://caselaw.lp.findlaw.com/scripts/ts_search.pl?title=18&sec=2252 I don't know of any cases where that law has been applied to poser images, but quite frankly, the code is broad enough to allow a prosecutor to nail even cartoons of naked kids. Certainly poser has more quality capability than that. And, its not necessary to be involved in commerce or transportation (though posting an image for download would be a type of transportation). To be on the safe side, the debate will likely end in not allowing any image that even brushed close to that code.
